That's a bit strange. I would suggest to return the removed lines instead, or to pass a `Consumer<String>` (or even better, a `Predicate<String>`  ?) that will accept the removed lines. You could continue to remove if the predicate returns true and throw if it returns false. It would also enable you to tell exactly which line failed the check.
